The historic Targ Węglowy Square in Gdańsk, Poland was merely an empty lot before the Gdyby Group (whose name translates to "What if?") in collaboration with City Culture Institute proposed a new public space to revive it.

Back in early September, the group installed the numerous cubic box furnishings throughout the lot, where visitors of any age can play, socialize, and relax. Gdyby then gathered public feedback on the project and held an open public discussion about the Square's future.
